the momentum must be greater than the force . the force may be very large
work=mass*speed,5*2=10
Assuming the impact was elastic, Car1 will not be at rest, and Car2 will move at 20m/s at the same direction Car1 was previously moving.
If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.
